Doctor diagnosed terminal cancer in dinosaur | Science



This is not the first time that cancer has been found in fossil remains. Scientists have found benign tumors in Tyrannosaurus Fossils and arthritis in hadrosaurs, and osteosarcoma in 240 million-year-old turtles. But the researchers say their study is the first to confirm the diagnosis of dinosaur cancer at the cellular level.

Scientists including paleontologists, pathologists, surgeons, and radiologists used high-resolution computed tomography to examine the entire fossil and examined thin sections under a microscope to assess the structure of the cells. They found that the tumor had developed enough to bother the animals for some time. They wrote that similar untreated human cases are likely to be fatal. However, since fossils were found in the fossil bed, there are many other Center Dragon Among the specimens, the dinosaurs probably died in the flood, while the rest were not cancer.

The researchers said that their diagnosis showed that the use of modern imaging and diagnostic techniques allows for closer observation of abnormal fossil deformities, thereby gaining new insights into the evolutionary origin of the disease.
